Here you can set up footer logo, background, write your own copyright text and enable / disable footer social icons or scroll up link.
Generally, to set up site footer logo, social, copyright.., you can go to Customize > Footer panel.
Before footer bottom area, there’s an area called Footer sidebar.
Note that, if you wanna set up footer widgets, please go to Dashboard > Appearance > Widgets and drop your widgets in to Footer Sidebar. In our demo, we used Instagram widget in this area. But you can add any widget you want to.
